New Post: SPCascadeDropdowns working in IE10 but not IE11

I think this is probably a known issue, but I haven't been able to find a workaround on my own so far. I've got the following script loading in my web part. The script filters the list of names available in a multi-lookup column so that only those people from the same territory as the current list item appear on the left side. It works like a charm in IE10, but doesn't filter the available names in IE11 or Chrome.

<script type="text/javascript">
$(document).ready(function() {
    $().SPServices.SPCascadeDropdowns({
        listName: "Project Bids",
        relationshipList: "Bidders",
        relationshipListParentColumn: "Territory",
        relationshipListChildColumn: "Full_x0020_Name",
        parentColumn: "Territory",
        childColumn: "Bidders"
    });

});
</script>
